Eisenia arborea is an edible brown alga occasionally used as a folk medicine in gynecopathy in Japan. A new phlorotannin was isolated from the alga during our search for naturally occurring anti-allergic compounds from edible algae guided by the inhibitory effect on histamine release from rat basophile leukemia (RBL)-2H3 cells. The phlorotannin was called "phlorofucofuroeckol-B." Its structure was determined by spectral analysis and chemical conversion. This paper describes the isolation, structure elucidation, and inhibitory effect of phlorofucofuroeckol-B on histamine release.
树状艾氏藻是一种可食用的褐藻,在日本偶尔被用作妇科的民间药物。在我们以对大鼠嗜碱性白血病(RBL)-2H3细胞组胺释放的抑制作用为指导,从可食用藻类中寻找天然抗过敏化合物的过程中,从该藻类中分离出了一种新的间苯三酚鞣质。这种间苯三酚鞣质被称为“间苯三酚岩藻呋喃醚醇-B”。其结构通过光谱分析和化学转化确定。本文描述了间苯三酚岩藻呋喃醚醇-B的分离、结构解析及其对组胺释放的抑制作用。
